摘　　要：易燃易爆液体的实时、远程和动态探测对于保障公共安全具有重要意义,在公安、民航和海关等领域应用前景广阔。本文在对典型易燃易爆液体和水的光谱分析的基础上,研制了一种基于三个不同波长的近红外激光照明的多光谱成像系统,并开展了对典型易燃易爆液体的探测试验,结果表明该系统对静态目标和速度小于1m/s的运动目标探测精度高于95%。Based The flammable liquid detection, especially flammable liquid remote dynamic monitoring, was of great importance to civil aviation, customs and public security. For the purpose, a near infrared ray （NIR） laser illu- minated multi-spectral imaging system was developed based on the result of spectrum analysis of typical flammable liq- uid. The experimental results show that the laser illuminated multi-spectral imaging system can reach more than 95% accuracy when the movement speed of liquid object was less than 1m/s.
